Aim
Incisional hernia are an established complication following abdominal surgery. There is limited data available on the relationship between formation of an incisional hernia and choice of extraction site for patients undergoing a laparoscopic anterior resection. This study aimed to determine the prevalence of incisional hernia following this operation and any potential link at our centre with choice of extraction site.

Method
All patients who underwent laparoscopic anterior resections over a 3-year period between 2015 and 2017 were identified from a local hospital database at a single centre. Patients were divided into 3 groups based on specimen extraction site (left iliac fossa, midline and pfannenstiel). All patients included in the study had a minimum of 4 years follow up. Patients who developed incisional hernia were identified through reviewing clinical notes and follow up imaging. Data regarding demographics, presentation and outcome were collected from these patients.

Results
A total of 95 patients underwent laparoscopic anterior resections. The total incidence of incision hernia across all groups was 10.5% (n = 10). The total incidence of incisional hernia at the site of specimen extraction was 7.4% (n = 7). The median time between operation and hernia diagnosis was 11.5 months (range 1–39 months). A higher rate of incisional hernia was noted in those with a left iliac fossa extraction site (n = 5, 14.7%), when compared to those with a midline extraction site (n = 2, 6.9%). No extraction site hernia were identified in patients with a pfannenstiel incision.

Conclusion
Incisional hernia were more common at specimen extraction sites compared to other incisional sites following laparoscopic anterior resection. No statistical significance was found between incisional hernia rates and extraction sites within our sample. Future studies with larger sample sizes are needed to investigate the potential correlation between incisional hernia and choice of specimen extraction site.
